I am using Xcode 9.2 
1) I have copy the SQLite.xcodeproj file into my project.
2) In the ViewController, i used the following 
import SQLite
Problem:
 when I do the achive ( Product>Archive) , there is a compile error message:
 No such module 'SQLite'
 If I do normal compile : CMB + B, no issue. 
Please help. What I need to do?
Update:
I followed these approaches but all failed. Where went wrong?
1) Shift+Alt+Command+K
 after this, then CMD + B to. compile Same error msg as above.
2) As of Xcode 9 you'll be able to access the Derived Data folder by navigating to
File -> Project Settings 
  press the arrow to go to the DerivedData folder
 I removed it to trash
after this, then CMD + B to. compile Same error msg as above.
3)Open terminal and past the following:
rm -rf ~/Library/Developer/Xcode/DerivedData
after this, then CMD + B to. compile Same error msg as above.
Update:
I realized the SQLite is older version before I upgraded to Xcode9.2.
To solve the problem:
Delete the old one, and install the the New SQLite for Xcode 9
